Make using '-fshort-enums' an error until it is actually implemented (changes the ABI, so it is dangerous to not error out if we don't support it).  Fixes <rdar://problem/7461006>.

While scanning through the uses of an alloca, keep track of the current offset
relative to the start of the alloca, and check memory references to see if
the offset & size correspond to a component within the alloca.  This has the
nice benefit of unifying much of the code from isSafeUseOfAllocation,
isSafeElementUse, and isSafeUseOfBitCastedAllocation.  The code to rewrite
the uses of a promoted alloca, after it is determined to be safe, is
reorganized in the same way.

Also, when rewriting GEP instructions, mark them as "in-bounds" since all the
indices are known to be safe.

scan-build: when the build command is 'make', override the CC and CXX options by passing them as arguments to make.  This fixes <rdar://problem/6790224>.

Tests: Change substitution to automagically use 'clang -cc1' instead of 'clang-cc'. I still plan to eventually rewrite the tests to clarify the magic (I will probably actually rewrite them to %clang so it is more obvious this is a variable that gets substituted).

 - I apologize for the link time horrors, my goal is to kill off clang-cc in fairly short order.

branches only to a landing pad. Without this check, the compiler would go into
an infinite loop because the branch to a landing pad is an "abnormal" edge which
wasn't being taken into account.

This is the meat of that fix:

  if (!PrevBB.canFallThrough() && !MBB->BranchesToLandingPad(MBB)) {

The other stuff is simplification of the "branches to a landing pad" code.
